not really a showcase, but I wanted to get some Hyperion leds hanging off my access point. I noticed my net gear r8000 with dd-wrt support sharing its USB points over the network with usbip. A quick test with the adalight arduino sketch seems to work great. Hyperiond is running on a ubuntu 16 virtual machine with the adalight protocol talking to /dev/ttyUSB0 Usbip was setup on the r8000 with the physical usb device to be shared over the network: Code: [email protected]:~# usbip list -l - busid 2-1 (0403:6001) Future Technology Devices International, Ltd : FT232 Serial (UART) IC (0403:6001) [email protected]:~# usbip bind -b 2-1 usbip: info: bind device on busid 2-1: complete Usbip was setup on the ubuntu box to bind the remote device that's plugged into the r8000. Code: apt-get install linux-cloud-tools-generic linux-tools-common linux-tools-generic [email protected]:~# usbip list -r r8000 usbip: error: failed to open /usr/share/hwdata//usb.ids Exportable USB devices ====================== - r8000 2-1: unknown vendor : unknown product (0403:6001) : /sys/devices/pci0000:00/0000:00:0b.0/usb2/2-1 : (Defined at Interface level) (00/00/00) [email protected]:~# modprobe vhci-hcd [email protected]:~# usbip attach -r r8000.home -b 2-1 [email protected]:~# dmesg | tail -5 [ 179.588246] usbcore: registered new interface driver ftdi_sio [ 179.588246] usbserial: USB Serial support registered for FTDI USB Serial Device [ 179.588446] ftdi_sio 2-1:1.0: FTDI USB Serial Device converter detected [ 179.588446] usb 2-1: Detected FT232RL [ 179.591686] usb 2-1: FTDI USB Serial Device converter now attached to ttyUSB0 Hope this is of some use to someone - if anyone's interested I can provide more specific details.
I just did some quick network traffic measurements on this setup. Setup: hyperion (not hyperion.ng) with 46 leds "type" : "adalight", "output" : "/dev/ttyUSB0", "rate" : 115200, smoothing disabled 1) usbip configured but hyperiond NOT running - 0 bytes/sec 2) hyperiond idle - 6K byte/sec 3) hyperiond running rainbow swirl fast - 14K byte/sec I havent measured the latency, but rapidly changing the colours on the iphone app doesnt show any lag
